How to display handlebars image?

Question

Node.js

I have a small dilemma using multer to load an image.
The image that I upload I want to display on the next page, how can I do this?

router.post('/upload', (request, response) => {
    upload(request, response, (error) => {
        if(error) {
            request.flash('error_message', 'Only images are allowed')
            response.redirect('/')
        }
        else {
            if(request.file == undefined) {
                request.flash('error_message', 'Image file was not been selected.')
                response.redirect('/')

                console.log(request.file)
            }
            else {
                request.flash('success_message', 'Image was uploaded successfully.')
                response.redirect('/compress')

                console.log(request.file)
            }
        }
    })
})

router.get('/compress', (request, response) => {
    response.render('compress')
    file: `uploads/${request.file}`
})

<img class="uploadedImage" src="uploads/{{file}}"></img>

Either save a link to the image somewhere in the database/session, and issue it from there (because the request for each new request will be clean, the old file will definitely not be there), or pass it as a GET request parameter, and from there look output. You can pass it through request.flash, it uses the session.
